Technical Field

[0001] The present application relates to the field of Chinese medicinal herb extraction, and in particular to an extract separation device. Background Art

[0002] Chinese herbal medicine extraction refers to the process of extracting effective ingredients from Chinese herbal medicines through a series of technical means. The extraction process often uses an extraction tank as an extraction device. The working principle of the extraction tank is mainly a simple decoction process. The material is immersed in a pre-tank filled with a solvent, and then heated and circulated. After a period of time, the effective components in the material are analyzed and finally form a medicinal extract.

[0003] However, in the process of implementing relevant technical solutions, at least the following technical problems were found: after the medicinal materials are taken out, the material receiving trolley is first moved to the bottom of the extraction tank, the bottom cover is opened, and the residue is unloaded from the bottom of the extraction tank. The bottom cover is hinged on the tank body, and the bottom cover is driven to open and close by a hydraulic cylinder installed on the tank body. The gravity generated by the material in the tank body acts on the bottom cover. After the bottom cover is closed, the hydraulic cylinder must continue to provide force so that the bottom cover can support the gravity of the material. The gravity generated by the liquid and material in the extraction tank is all resisted by the force of the hydraulic cylinder, which will cause the hydraulic cylinder to continue to bear a large load and pose a certain safety hazard. Summary of the invention

The present application realizes that after the tank bottom end cover is closed, the hydraulic cylinder and the connecting rod structure both bear the downward pressure of the tank bottom end cover, which reduces the load on the hydraulic cylinder and improves the closing safety of the safety tank bottom end cover.

[0006] Furthermore, the driving mechanism also includes: an extension rod, one end of which is fixed to the connecting bar and the other end extends to one side of the short connecting rod 2, and the length direction of the extension rod is consistent with the length direction of the connecting bar; a blocking cloth is fixed between the extension rod and the long connecting rod 2.

[0007] Furthermore, the long connecting rod 2 includes a long rod section and a short rod section, the long rod section is hinged to the connecting strip, the short rod section is hinged to the short connecting rod 2, the angle between the long rod section and the short rod section toward one side of the extension rod is an obtuse angle, and one side of the cloth retaining cloth is fixed on the short rod section.

[0008] Furthermore, the blocking cloth is a folding cloth. The blocking cloth is in a folded state when the tank bottom end cover is in a closed state, and is in an unfolded state when the tank bottom end cover is in an open state.

At this time, the baffle cloth will gradually unfold, and the unfolded baffle cloth part will be below the bottom end cover of the tank body. Therefore, when the material in the tank body is unloaded, the baffle cloth on both sides will play a blocking role, preventing the material from spreading to both sides, which is conducive to the material falling vertically into the material cart below.

DETAILED DESCRIPTION

[0021] The embodiment of the present application discloses an extract separation device. When the tank bottom end cover 1 is opened, the blocking cloth 38 will gradually unfold during the opening process of the connecting rod in the driving mechanism 3. The unfolded blocking cloth 38 part will be below the tank bottom end cover 2. Therefore, when the material in the tank body 1 is unloaded, the blocking cloth 38 on both sides will play a blocking role, preventing the material from spreading to both sides, which helps the material to fall vertically into the material cart below. Moreover, through the connecting rod in the driving mechanism 3, when the tank bottom end cover 1 is closed, the supporting force formed by each connecting rod can bear part of the downward pressure of the tank bottom end cover 1, reducing the load of the hydraulic cylinder 32, and solving the technical problem that the gravity generated by the liquid and material in the extraction tank in the prior art is entirely resisted by the force of the hydraulic cylinder, which will cause the hydraulic cylinder to continuously bear a large load and have certain safety hazards. It is achieved that after the tank bottom end cover 1 is closed, the hydraulic cylinder and the connecting rod structure both bear the downward pressure of the tank bottom end cover, reducing the load of the hydraulic cylinder and improving the closing safety of the safety tank bottom end cover.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 An extract separation device comprises a tank body 1, a tank bottom end cover 2, and a driving mechanism 3. The tank body 1 is cylindrical and has an opening at the bottom. The tank bottom end cover 2 is used to seal the bottom opening of the tank body 1. After the tank bottom end cover 2 is covered on the tank body 1, the edge of the tank bottom end cover 2 protrudes from the outside of the outer wall of the tank body 1. The driving mechanism 3 is provided with two groups and is symmetrically arranged on the outer walls on both sides of the tank body 1. The two driving mechanisms 3 are connected to the edges of the two sides of the tank bottom end cover 2. The two driving mechanisms 3 run synchronously and open and close the tank bottom end cover 2.

[0024] Reference Figure 2 and Figure 3The driving mechanism 3 includes a connecting bar 31, a hydraulic cylinder 32, a long connecting rod 1 33, a short connecting rod 1 34, a long connecting rod 2 35, a short connecting rod 2 36, an extension rod 37, and a stop cloth 38. The connecting bar 31 is a bar column with a rectangular cross section, and the connecting bar 31 is welded to the edge of the tank bottom end cover 2. When the tank bottom end cover 2 is closed, the connecting bar 31 of the driving mechanism 3 on both sides is parallel to each other, and both ends of the connecting bar 31 are hinge points, and the hinge axis of the hinge point is perpendicular to the length direction of the connecting bar 31. The hinge axis of one end of the connecting bar 31 is on the vertical plane where one of the diameter lines in the tank bottom end cover 2 is located, and one end of the extension rod 37 is fixedly connected to the connecting bar 31 and is located on the outer side wall of one end of the hinge point, and the other end of the extension rod 37 extends to the side away from the connecting bar 31, and the length direction of the extension rod 37 is consistent with the length direction of the connecting bar 31. The hydraulic cylinder 32 is installed on the outer wall of the tank body 1, and the cylinder seat of the hydraulic cylinder 32 is hinged on the outer wall of the tank body 1, the hinge axis of the cylinder seat of the hydraulic cylinder 32 is horizontal, and the hinge axes of the cylinder seats of the hydraulic cylinder 32 in the driving mechanisms 3 on both sides are collinear. When the tank bottom end cover 2 is in a closed state, the position where the connecting strip 31 is fixedly connected to the extension rod 37 is located directly below the cylinder seat of the hydraulic cylinder 32, and the telescopic rod of the hydraulic cylinder 32 is located on the side away from the extension rod 37.

[0025] Continue to refer to Figure 2 and Figure 3 The long connecting rod 33 is longer than the short connecting rod 34. When the tank bottom end cover 2 is in the closed state, the long connecting rod 33 and the short connecting rod 34 are both located on the side away from the extension rod 37 at the connection between the connecting strip 31 and the extension rod 37. One end of the long connecting rod 33 is hinged to the hinge point of the end of the connecting strip 31 at the connection with the extension rod 37, and the other end is hinged to the outer wall of the tank body 1. One end of the short connecting rod 34 is hinged to the connecting strip 31 at the connection with the extension rod The other end is hinged on the hinge point of the other end where the long connecting rod 33 is connected with the tank body 1, and the other end is hinged on the outer wall of the tank body 1. The hinge point between the long connecting rod 33 and the tank body 1 is located above the hinge point between the short connecting rod 34 and the tank body 1. The hinge points of the long connecting rod 33 and the short connecting rod 34 with the tank body 1 are both located on one side of the hydraulic cylinder 32 and on the side of the connecting strip 31 that is hinged with the short connecting rod 34. In addition, the telescopic end of the hydraulic cylinder 32 is hinged to the middle part of the long connecting rod 33.

[0026] Continue to refer to Figure 2 and Figure 3One end of the long connecting rod 35 is hinged on the connecting bar 31, and the other end is located on the side of the hydraulic cylinder 32 away from the long connecting rod 1 33. The hinge axis between the long connecting rod 35 and the connecting bar 31 is collinear with the hinge axis between the long connecting rod 1 33 and the connecting bar 31. In addition, the long connecting rod 35 includes an integrally formed long rod section 351 and a short rod section 352. The length of the long rod section 351 is greater than the short rod section 352, and there is an angle between the long rod section 351 and the short rod section 352. The end of the long rod section 351 in the long connecting rod 35 is hinged to the connecting bar 31, and when the tank bottom end cover 2 is in the closed state, the angle between the long rod section 351 and the short rod section 352 toward the extension rod 37 is an obtuse angle. The short connecting rod 2 36 is located on the side of the long connecting rod 2 35 away from the hydraulic cylinder 32. One end of the short connecting rod 2 36 is hinged on the outer wall of the tank body 1, and the other end is hinged to the end of the long connecting rod 2 35 away from the connecting strip 31. When the tank bottom end cover 2 is closed, the hinge point between the short connecting rod 2 36 and the long connecting rod 2 35 is located above the hinge point between the short connecting rod 2 36 and the tank body 1, and the angle between the short connecting rod 2 36 and the long connecting rod 2 35 is an acute angle. In addition, a plurality of support blocks 11 are fixed on the outer wall of the tank body 1, and a support rod 12 is fixed to the support block 11. The ends of the long connecting rod 1 33, the short connecting rod 1 34, and the short connecting rod 2 36 that are hinged to the tank body 1 are hinged to the respective support rods 12, respectively. By using the support blocks 11 and the support rods 12, the hinge points of the respective connecting rods can be at similar positions in the vertical direction, which is conducive to ensuring the stability of the driving mechanism 3 during operation.

[0027] Reference Figure 2 and Figure 3 As shown, the hydraulic cylinder 32 in the driving mechanism 3 is in a contracted state, the connecting bar 31 is in a horizontal state, the tank bottom end cover 2 is in a state of sealing the bottom opening of the tank body 1, and the angle between the short connecting rod 2 36 and the long connecting rod 2 35 is an acute angle, so that the short connecting rod 2 36 can support the long connecting rod 2 35, and also support the tank bottom end cover 2, reducing the load of the hydraulic cylinder 32. Figure 4 and Figure 5 The hydraulic cylinder 32 in the driving mechanism 3 is in an extended state. The extension of the hydraulic cylinder 32 will push the long connecting rod 33 to swing downward, and under the action of the short connecting rod 34, the bottom end cover 2 of the tank will completely break away from the bottom opening of the tank body 1 and open to one side. Finally, the bottom opening of the tank body 1 will be completely exposed, which is conducive to faster unloading of materials and reduces the possibility of materials being blocked on the bottom end cover 2 of the tank.

[0028] Reference Figure 2 , Figure 4 and Figure 5As shown, the blocking cloth 38 is made of high temperature resistant material, is a folded cloth and is fan-shaped, one side of the blocking cloth 38 is fixed to the extension rod 37, and the other side is fixed to the long rod section 351 of the second long connecting rod 35. When the tank bottom end cover 2 is in a closed state, the blocking cloth 38 is in a folded state. When the tank bottom end cover 2 is opened, the angle between the extension rod and the second long connecting rod 35 gradually increases, and the blocking cloth 38 will gradually unfold, and the unfolded part of the blocking cloth 38 will be below the tank bottom end cover 2. Therefore, when the material in the tank body 1 is unloaded, the blocking cloth 38 on both sides will play a blocking role, preventing the material from spreading to both sides, which helps the material to fall vertically into the material car below.

[0029] This application can explain its functional principle through the following operation methods:

[0030] The separation process of the medicinal material extract is realized in the tank body 1. A large amount of material and solvent will be introduced into the tank body 1, and the tank bottom end cover 2 will bear the weight of a large amount of material and solvent. When the tank bottom end cover 2 is closed, the telescopic rod of the hydraulic cylinder 32 in the driving mechanism 3 is in a contracted state. The hydraulic cylinder 32 is used to ensure that the tank bottom end cover 2 is in a tightly closed state and bears the downward pressure of the tank bottom end cover 2. The angle between the short connecting rod 2 36 and the long connecting rod 2 35 in the driving mechanism 3 is an acute angle at this time. The short connecting rod 2 36 can support the long connecting rod 2 35, and also support the tank bottom end cover 2, and can bear part of the downward pressure of the tank bottom end cover 2, thereby reducing the load of the hydraulic cylinder 32 and improving the closing safety of the safety tank bottom end cover 2.

[0031] When unloading is required, the material trolley will stop below the bottom of the tank body 1 in advance, and then the hydraulic cylinder 32 will be started to extend the telescopic rod of the hydraulic cylinder 32, and the telescopic rod of the hydraulic cylinder 32 will push the long connecting rod 1 33 to swing downward, and under the action of the short connecting rod 1 34, the tank bottom end cover 2 will completely break away from the bottom of the tank body 1 and open to one side. In this process, the angle between the short connecting rod 2 36 and the long connecting rod 2 35 gradually increases, and the extension rod also swings downward synchronously, and the angle between the extension rod and the long connecting rod 2 35 gradually increases. At this time, the baffle cloth 38 will gradually unfold, and the unfolded part of the baffle cloth 38 will be below the tank bottom end cover 2. Therefore, when the material in the tank body 1 is unloaded, the baffle cloth 38 on both sides will play a blocking role, preventing the material from spreading to both sides, which helps the material to fall vertically into the material cart below.

Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
